^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) The WM835x series of PMICs include an AUXADC which can be used to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) monitor a range of system operating parameters, including the voltages
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) of the major supplies within the system. Currently the driver provides
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) simple access to these major supplies.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) ------------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) Voltages are sampled by a 12 bit ADC. For the internal supplies the ADC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) is referenced to the system VRTC.
